Patent CA-2288105-C (CA)
Inventor: ISHII MASARU
IPC: B01J29/068
Filed: 1998-04-22
Granted: 2002-08-06
Abstract: An exhaust gas purification method and an exhaust gas purification catalyst which, even when the exhaust gas is in a oxygen-rich atmosphere, can surely exhibit a high NOx conversion. The method permits NOx in an exhaust gas in an oxygen-rich atmosphere to be converted by reduction. The catalyst comprises a carrier layer comprising mordenite, aluminum sulfate and cerium zirconium sulfate composite oxide supported on the carrier layer, and Pt further supported thereon. In a temperature region where hydrocarbon is not oxidized, it is adsorbed and held by mordenite, and the hydrocarbon released from the mordenite at the time of temperature elevation is cracked by the mordenite, aluminum sulfate, and cerium zirconium sulfate composite oxide, thus reducing NOx in the exhaust gas with the lower hydrocarbon produced by the cracking as a reducing agent.

Granted: 2008-01-29
Abstract: A highly efficient process for the production and recovery of pure succinic acid from a succinate salt that involves minimal use of additional reagents, and produces virtually no waste by-products, and permits internal recycle of the base and acid values, is provided. The method involves the formation of diammonium succinate, either by using an ammonium ion based material to maintain neutral 8 pH in the fermenter or by substituting the ammonium cation for the cation of the succinate salt created in the fermenter. The diammonium succinate can then be reacted with a sulfate ion, such as by combining the diammonium succinate with ammonium bisulfate and/or sulfuric acid at sufficiently low pH to yield succinic acid and ammonium sulfate. The ammonium sulfate is advantageously cracked thermally into ammonia and ammonium bisulfate. The succinic acid can be purified with a methanol dissolution step. Various filtration, reflux and reutilization steps can also be employed.

Title: Method and apparatus of producing liquid disperse systems in liquid
Inventor: KOZYUK OLEG VYACHESLAVOVICH
IPC: B01F3/08
Filed: 1999-02-05
Granted: 2007-01-09
Abstract: A method and apparatus for producing a liquid disperse system in a flow-through channel is described. The flow-through channel (1) has first and second chambers (4, 5). The liquid in the first chamber (4) is maintained at a steady pressure P1-. The liquid is passed through a localized flow constriction (2) creating cavitation liquid jets that flow into the second chamber (5). The dynamic pressure of the liquid jets is govern by the equation pv2/2>=0.15 P1 where p is the density of the cavitation liquid jet and v is the velocity of the cavitation jet. Cavitation bubbles are produced in the cavitation liquid jets between 1 x 10-6 m and 1 x 10-2 m. The pressure in the second chamber P2 is maintained such that P1/P2 is <=9.8. The liquid disperse system is produced by the collapsing of the cavitation bubbles under static pressure P2 an the second chamber. The pressure P2 in the second chamber is maintained by a localized resistance at an outlet of the second chamber (5). The localized flow contraction may be shaped to produce cavitation liquid jets which are cylindrical, ring-shaped, or flat shaped. The liquid flow may be passed through the flow-through channel a number of times to further increase the production of liquid disperse systems.

Title: Technique for parametric coding of a signal containing information
Inventor: SINHA DEEPEN
IPC: G10L19/00
Filed: 2000-11-22
Granted: 2004-02-03
Abstract: In a communications system, parametric coding in accordance with the invention is implemented to generate a representation of a stereo audio signal, which is composed of a left channel signal (L) and a right channel signal (R). To efficiently utilize transmission bandwidth, such a representation contains (1) information concerning only one of the L and R signals, and (2) parametric information based on which, together with (1), the other signal can be recovered. Because of the design of the parametric coding, the representation advantageously captures localization cues of the stereo audio signal, including intensity and phase characteristics of L and R. As a result, tie stereo audio signal recovered from the transmitted representation affords a high stereo quality.

Abstract: The present method provides a method for inhibiting restenosis associated with mechanical injury of a blood vessel. Human heme oxygenase (I) (HO1) is directly administered at the site of injury.

Abstract: Selon cette invention, le boîtier (4) d'un amortisseur comprend une chambre interne (10) entourée par une chambre externe (30). La chambre interne est divisée par le piston (12) auquel est reliée dans deux parties la tige de piston (11). Une de ces parties comporte un certain nombre d'orifices qui relient cette partie par fluides à la chambre externe. Un piston (32) disposé coulissant et mobile le long de la chambre externe divise la chambre externe en deux compartiments dont un se trouve en communication fluidique avec la partie de la chambre interne à laquelle il est relié par les orifices. Un fluide incompressible remplit le compartiment et la partie qui communiquent par fluide. Une force de sollicitation agit sur le piston dans la chambre externe sous l'effet d'un gaz comprimé remplissant l'autre compartiment de la chambre externe. Grâce à cette construction de l'amortisseur, lorsque la tige de piston se déplace, le piston (12) auquel elle est reliée provoque un échange de fluides entre la chambre interne et la chambre externe, qui sert de réservoir. La taille des orifices et la pression du gaz qui agit sur le piston dans la chambre externe (30) contribuent à définir la rigidité de l'amortisseur.
